Dead space in lung ventilation

WebRemember that tidal volume is the sum of dead space volume and alveolar volume, so in this diagram 500mL of tidal volume will be composed of 150mL dead space volume and 350mL alveolar volume. Hence, we can deduce alveolar ventilation by multiplying respiratory rate (15/min) and alveolar volume (350mL) to get 5250mL/min. WebBoth produce dead space or shunts, regions of ineffective lung tissue. Dead spaces can severely impact breathing, because they reduce the surface area available for gas …
